Yi said making industry more intelligent was key to helping unleash the potential in western China and promoting economic transformation.

In Chongqing, the two pillar industries of autos and electronics have been contributing less and less to the local economy due to a variety of factors, including fierce competition and constraints in market size.

The city is turning to digital economy for more growth momentum. It is developing intelligent industries such as big data, AI and intelligent hardware and using big data and intelligent technologies to upgrade traditional industries.

Chongqing has pledged to support the development of 12 high-tech industries, including big data, AI, intelligent robot and connected cars, aiming to achieve a combined output value of 750 billion yuan (108.8 billion U.S. dollars) in 2020, and 1 trillion yuan in 2022.

Some of the high-tech solutions have helped improve efficiency. A facial recognition system has been deployed at a Chongqing airport to help quicken security checks.

Passengers go to security channels where cameras can capture their facial images and scan their ID cards to verify their identities in seconds, thus avoiding long queues at airport security checkpoints.

"The facial recognition system can spare us the trouble of waiting too long for check-in formalities," said Zhang Minmin, who recently experienced the fast service at the airport.

Cloudwalk, developer of the intelligent security check system in Chongqing, has deployed the system at more than 60 airports nationwide.
